Alexander Bain
Created | Updated Jan 28, 2002
Born in the little town of Thurso, at the extreme north of Scotland, in the year 1811. At the age of twelve he went to hear a penny lecture on science which, according to his own account, set him thinking and influenced his whole future. Learning the art of clockmaking, he went to Edinburgh, and subsequently to London, where he obtained work in Clerkenwell, then famed for its clocks and watches.
Bains first patent is dated January 11th, 1841, and is in the name of John Barwise, chronometer maker, and Alexander Bain, mechanist, Wigmore Street. It describes his electric clock in which there is an electro-magnetic pendulum, and the electric current is employed to keep it going instead of springs or weights. He improved on this idea in following patents, and also proposed to derive the motive electricity from an 'earth battery,' by burying plates of zinc and copper in the ground.
On December 12, 1846, Bain, who was staying in Edinburgh at that time, patented his greatest invention, the chemical telegraph, which bears his name. He recognised that the Morse and other telegraph instruments in use were comparatively slow in speed, owing to the mechanical inertia of the parts; and he saw that if the signal currents were made to pass through a band of travelling paper soaked in a solution which would decompose under their action, and leave a legible mark, a very high speed could be obtained. This process was later modified to create the first facsimilie.
In England the telegraph of Bain was used on the lines of the old Electric Telegraph Company to a limited extent, and in America about the year 1850 it was taken up by the energetic Mr. Henry O'Reilly, and widely introduced. But it incurred the hostility of Morse, who obtained an injunction against it on the slender ground that the running paper and alphabet used were covered by his patent. By 1859, as Mr. Shaffner tells us, there was only one line in America on which the Bain system was in use, namely, that from Boston to Montreal. Since those days of rivalry the apparatus has never become general, and it is not easy to understand why, considering its very high speed, the chemical telegraph has not become a greater favourite.
